eswc- COOKING-move.

The Schedule referred to in these Letters Patent and making part of the same I, Josera B. WILKINSON, of the ,city of Troy, county of Rensselaer and State o f N ew York, have invented certain Improvements in Cooking-Stoves, of which the following is a spccication.

The nature of my invention eonslsts'in the extension backward ofthe sheetdiue, always situated above the oven and below the top plate of the stove. Said sheet-flue has heretofore ended with the front line of the back vertical dues-of the stove.

These back fines in myv stove arc vdiscontinued and not carried up above the top plate of the oven, so that whether the vstore be one having two vertical back fines, or one having three back vertical fines, there a'e nc descending lines above the line of the top oven p ate.

The top oven plate covers all'the `back vert-ical dues, whether one or more, and the space above the top plate ofthe oven, and between it and the top-plate of the stove, and from. side to side or'jainb to jamb of the stove, and from the bac-kof stove to front, becomes one broad sheet-fine; and the part or portion thereof back of the line ofthe back plate of the oven, o1' back of the usual limit or back line of the sheetflue, as formerly used, is the extension which I claim as new, and as my invention.

The extending of thetop oven-plate over and beyond the back vertical dues of the stove, being the subjectof a former patent, is not'claimed in this.

The nature of my invention also consists in placinga pipe-collar upon the said top'oven-plate ofthe stove, extending the same upward through an aperture in the top plate of the stove, fitting tightly,and sufriciently above said top plate to permit the placing of the exit-pipe or stove-pipe thereon.

The said pipe-collar may be cast or constructed as a part of the top oven-plateifreqnired.

It also consists in having a damper, or itscquivalent, situated at the back of said pipe-collar, covering an opening therein, so that the escaping products of combustion may bc permitted to enter said pipe-collar from the above-mentioned extended lflue-space, and pass off to the exit-pipe, when necessary.

At the backv of my stove I place a water-reservoir or tank.

rlhc extended liuc-space above mentioned reaches backward to the front wall of the reservoir or tank, so that an open space is formed all along the front wall of the said reservoir or tank, andfrom the top ovenplate upward to the top plate of the stove.

There being no back plate at this place in a stove of my construction, the reservoir or tank forms vthe back of the extended sheet-flue above described.

And the object of the extended flue-space is, so that the products of combustion, heat, tbc., may pass freely along the entire front of the reservoir or tank so that water therein may be heated for culinary pu'rposes.

rIhe object of the pipe-collar extending from the `top oven-plate upward, and resting thereon, is so that the products of combustion, smoke, &c.,'in escaping from the ascending flue of the stove, which is'situated below the top oven-plate extended, may pass upward to the exit-pipe or stove-pipe without obstructing the free circulation of heat, Sto., around in the extended sheet-flue above described, the shape orforrn of the pipe-collar being the best` thing for the purpose, as. it takes up but little space.

It may also be considered as an extensiondwn- .ward of the exit-pipe or stove-pipe, as I usually construct it of same size and shape. In that case it would be asif the stove-pipe passed downward through an aperture in the top plate of the stove to thetop plate of the oven extended, and resting on said top ovenplate. y

lhe said pipe-collar may be of any suitable material for the purpose'requircd.

The construction of the damper mentioned above permits a direct draught to be used without in any way-using the return fines of the stove at the back or bottom, and by meansof apertures through the top oven-plate extension the products of combustion (when the pipe-collar damper is closed) are passed downward out of and from said extended sheet-liuc into the rear vertical descending flue or fines ofthe stove, through the same to the bottom ducs of the stove, and return inthe usual manner.

Thecxtended top plate of the oven, or theequivalent thereof, and the construction of the reservoir or tank, and placing of the same, and also the apertures through' the saidextended top oven-plate, are all 'covered by a former application for which Letters Patent were granted, and consequently are not claimed inthis application; but the invention herein described and claimed is found of great importance in perfecting and rendering complete those claimed before, the stove, as perfected, being one of the most complete, economica-l, and useful ever constructed. It is also,

by these means, rendered one ofthe cheapest on sale y of any offered to the public.

The nature of my-invention also consists .in conthrough corresponding holes in and through the top plate of the stove, the object being to' keep the reservoir from any tendency to slide backward horizontally away from its junction or contact with the top plate or-strongly attached to the hack plate of the oven, and

the outer end or head attached to, in a suitable mauner,'the reservoir, so that the whole reservoir and stove-plates may be screwed or bolted up tightly tof gether, thereby making close and air-tight joints, the object beingto perfectly join the points of contact, and to firmly hold the plates together,l and also to prevent the escape of deleterious gases into the room within which the stove may be placed.

Another benefit t'be derived frouithe' construction of the extended top oven-plate, pipe-collar, and e'xtended tine-space, above mentioned, is, that the heat is concentrated rst against the reservoir before entering the rear vertical fines ot' the stove, and again it is strongly concentrated at the upper back corner of the oven, imparting intense heat-to the oven at that point, and here it is needed and highly beneficial.

Fresh or cold water may be supplied to the reservoir at any time wit-hout in anyway aii'ecting the temperature within the oven, and baking processes carried on perfectly, while water is freely used from' 'the reservoir,1 and fresh water-.added without in any way interfering with the oven. This'is not the case with stoves having v,reservoirs asheretofore used. The. oven in their case is sometimes cooled o" so rapidly as to-injure articles undergoing the usual processes within the oven. l

And still another useful feature derived from my manner of construction` is, that the reservoir may be heated by direct draught, water boiled therein, if necessary, and, in this case, utilizing the first heat of the stove, as, when kindling the fire, wood is used, and a 4direct draught needed, the vgreat heat given oiiy by the burning wood and kindlings commences to heat the reservoir as soon as fire is applied, and when the4 damper is sluit and return or reversed draught used, the water within the reservoir is kept at a proper de-V gree of temperature, I.and more perfectly' regulated than in the ordinary modes of construction.

The invention and improvements hereiudescribed may be'applied to any stove u sually made, having ascending and desceudingues, whether what is technically styled a two-flue, or what is so calleda three-flue stove, with either mode ot' construction, it works sat isfactorily and is highly beneficial.

Description. of the Accompanying Drawing.

Figure 1 is a perspective of the stove from the rear, with reservoir removed, and showing extended sheetflue and pipe-collar. The space at the hack left open is covered by the reservoir when in position.

Figure 2 is a lengthwise vertical section of the same construction, with reservoir.

Figure 3 is a lengthwise vertical section of the 1, but4 having the sheetline 'extended further back, so

that it passes over andv beyond the back vertical ilues, and-also back of the vrticalline of the back platev of the stove, which is carried out back at the top, for the purpose.

Figure 7 is a lengthwise vertical section ofthe same construct-ion.

Figure 8 is a horizontal section of the same above the oven.

Figure 9 is a lengthwise vertical section of asimilar stove, but having the reservoir set well down, the back oven-plate bent slightly forward, and the back plate of the stove bent but slightly backward.

Figure 10 is a horizontal section above the oven, corresponding therewith.

l.Figure 1l is a lengthwise vertical section of the back part of the stove, enlarged, so as to show the nibs or pins on the reservoir, and the bolts at' the back of the stove. t

, Figure 12 is a perspective of the back oven-plate, to correspond with iig. 11. v

' Figure 13 is a perspective of the reservoir, showing the flange, nibs or pins, bolts,&c.

There are two' sheets of drawing accompanying this spceiiication, marked respectively Sheet I and Sheet Like letters refer to like or corresponding parts. General Description.

A is the top-'oven plate;

B is the top lplate ofthe stove;

O is the back oven-plate ;I and D is the back plate of the stove.'

E is the reservoir;

E', the front wall or plate of the reservoir F is the pipe-collar G is the damper;1

H is the'sheet-lue above the oven; and

K is-the extension of said sheet-flue.

L L are the apertures through the top oven-plate A, hy means of which the products of combustionpass, before entering the rear or back vertical flues ot' the stove, to descendtothe bottom of the oven.`

There is also an aperture in the top oven-platc at M, situated at the top or upper end of the rear ascending-flue, and through 4this aperture the products of combustion pass, before entering' the pipe-collar F, in their escape to the exit-pipe or stove-pipe.

It will, be seen that 'when the pipe-collar is removed from the stove, there is aclear, openf,and unobstructed sheettlue or space abovelthe oven of the stove, and over the back or-'rcar vvertical iues, and reaching entirelyback t-o the front wall E of the reservoir, and it may be contiued further back, if deemed best, 'and used" for the same or similar purposes, and

when the pipe-collar F is in position, then that forins the only obstruction.

Allaround it and behindit is the extension of the broad sheetine H, the extended part marked K.

The pipe-collar F may be constructed small, so as to take up but little of what would be otherwise open space, and a great gain is eifected in concentrating the heat within the ascending-due of the stove, before it enters the pipe-collar F, imparting heat tothe oven,`

and also in retarding the products of combustion Iand extracting all theheat that would otherwise be wasted by too rapid escape to the eXit-pipe and, again, by

covering the descending vert-icaljiues of the stove, and

only admitting the products'of combustion through apertures of a suitable size, another gain is effected at this point, in concentrating the products of combustion -within the extended sheet-flue spaced, so as to impart a great heat to the reservoir, making it` an easy` mattei' to heat. water within. @he heat also being -saved greatlyat this point,.causes a saving of fuel of considerable importance; then, again, the intervention 'of the top. oven'fplate and sheet-flue vextension K is `suiicient to prevent the cooling of the oven, when fresh' waterl is added to the reservoir E.

vAnother gain is eifected'by this sheet-liuc extension Arrows show the direction of the diierent currents.

K, and situation of the pipe-collar F, in that of placing and constructing a regulating-damper at the back of said pipe-collar, which could not be done Without this mode of construction, and the advantages to be derived therefrom are considerable, for whether a reversed draught is used, when the damper' G is closed, or whether a direct; draught is used, and said daniper G open, in either case the products of Y combustion must pass back and around against the reservoir E, heating the water therein rapidly.

At R is the ange on the reservoir, to cover the joint or place of contact, and make all tight, and at S is the lugs or pins, to enter the corresponding holes in the top plate of the s tove,`and prevent the sliding backward horizontally of the reservoir, so as to open the joint or point of contact.

The reservoir in my construction is supported entirely by the top oven-plate A, Letters }?atent having already been granted to me covering that manner of supporting and sustaining a reservoir.

At l are shown the bolts, which pass through the back plate of the stove D, cross the rear vertical fines, and enter or are joined tothe back oven-plate C, and, by means of a nut at the outer end, bring the plates, all up tightly together, holding them firmly where wanted, and preventing the escape of the gases.

Projections are cast on the bottom of the reservoir, so that also, by means of these bolts, the reservoir can gases, Ste., into the room.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. For a diving-due'cooking-stove, ap'pc-collar, or its equivalent, resting on lthe top oven-plate, and extending up through the top plate of the stove, to receive a stove-pipe, substantially in manner and for the purpose described and set forth.

2. lhe extending of the top sheet-due of a cooking- AXGELIXE S. REILLE.
